Abstract: Thanks to deep learning, many computer vision tasks nowadays are formulated as the regression problem, from high-level vision tasks such as object detection and semantic segmentation, to middle-level tasks such as structure from motion, and low-level tasks such as image matching and optical flow. Often times one has to rely on huge amounts of annotated training data to succeed in this “curve-fitting” battlefield. However, computer vision can be more than a regression problem. In this talk, I will discuss a complementary yet overlooked problem beyond visual recognition and regression: discovering visual patterns in images and videos. I will discuss our recent work of visual pattern discovery, and explore how to utilize them to better summarize, search, and interpret visual data. Applications in object instance search, object detection, action recognition, and video summarization will also be discussed.
